The read
Busch Stadium gets a clear, calm Friday night for a division opener between two clubs whose strongest arguments come from different parts of the game.
Jared Jones gives Pittsburgh the more established starting-pitcher baseline: a 4.76 ERA and 1.25 WHIP across 15 starts, compared with Quinn Mathews’ 6.43 ERA and 1.79 WHIP through three. Jones has struggled recently, allowing 11 earned runs and ten walks over his last 12 innings, but Mathews is coming off ten hits and seven earned runs in five innings.
Neither offense owns a convincing handedness advantage. Pittsburgh has a .676 OPS against left-handed pitching, while St. Louis has a .693 OPS against right-handers. Mathews has allowed an .846 OPS to right-handed batters and faces six right-handed hitters plus two switch-hitters; Jones has allowed a .760 OPS to left-handed batters and faces five lefties.
The separation comes after the starters. Pittsburgh’s current bullpen carries a 3.14 ERA and 1.18 WHIP, against 4.05 and 1.30 for St. Louis. Over the last ten days, the comparison is 1.93 versus 7.96. Pittsburgh also had Thursday off, while St. Louis used five relievers and has Luis Gastelum, George Soriano and Riley O’Brien coming off consecutive appearances. Jones has not completed more than five innings in any of his last four starts, and Mathews has not exceeded five in any of his three, so those relief innings matter substantially.
St. Louis owns the better defense, with a .989 fielding percentage and 56 errors against Pittsburgh’s .982 and 84. The Pirates have also scored only 1.4 runs per game over their last five, compared with 4.4 for the Cardinals. Those concerns keep me away from Pittsburgh -1.5; the moneyline asks the stronger and better-positioned bullpen merely to help secure the win.

2Quinn MathewsUNDER 16.5 Pitcher Outs Pitcher Outs-130
LActual 17
Mathews has completed five, four and five innings in his three major-league starts, needing at least 95 pitches each time. This under still cashes if he records one out in the sixth.
St. Louis needs length after Thursday’s bullpen game, but need does not create efficiency. Mathews has issued seven walks in 14 innings, and Pittsburgh has enough patient hitters near the top to extend at-bats. I’m betting he reaches his pitch limit before recording a 17th out.
Jared JonesUNDER 15.5 Pitcher Outs Pitcher Outs-174
WActual 14
Jones has gone five innings or fewer in 12 of his 15 starts, including four straight. His recent innings totals are four, five, three and four, with ten walks consuming pitches over the last three outings.
Pittsburgh has managed his workload carefully since elbow surgery, and the rested bullpen removes any reason to stretch him. The price is heavy, but this line only loses if Jones records an out in the sixth.
